The Effect of the Method of Presenting Educational Materials in Multime-dia Learning Environment on Recalling Vocabulary with the Mediation of Verbal Fluidity

The aim of this study is to investigate the effects of the type of presenting educational materials (text only and text/picture) on vocabulary retention in the multimedia learning environment with the mediation of verbal fluidity. In this study, 78 students (45 female and 33 male) were randomly distributed into 6 thirteen-member groups in a multi-group pretest-posttest plan. The tools in this study were Tehran-Stanford-Binet intelligence test (TSB-R) and the researcher-made test of recalling words. The participants were randomly divided into test groups (control, verbal and picture-text) and screen size (big and small) groups. Before and after the tests, a retention was measured. The findings indicated that the text-picture group recalled fairly more words. Also, the members of this group in comparison with each other had closer performance. In addition, results indicated that the groups with bigger screen size recalled more words than the groups with smaller screen size. The findings about the mediation of verbal fluidity showed that it doesn’t have any effect on the subjects. The positive function of the text- picture explanations and screen size should be considered in planning the multimedia environment.
